Is oviposition time and oviposition interval associated with the deposition of cuticle on the hen’s egg?

British Poultry Science
1. The cuticle acts as a barrier to prevent microbial penetration of the eggshell. The reduction in the oviposition interval with selection for egg production and the activity of clock genes in the oviduct led to testing the hypothesis that the interval between successive oviposition of eggs would be related to the deposition of the cuticle. 2.

Soybean induced resistance to Spodoptera eridania herbivory

Pest Management Science, EarlyView.
SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

Cannibalism in Buchananiella whitei (Hemiptera: Anthocoridae) and its intraguild interactions with seven predatory mites (Acari: Phytoseiidae & Laelapidae)

Pest Management Science, EarlyView.
Extraguild prey reduces cannibalism and intraguild predation in Buchananiella whitei, while first‐instar nymphs dominate most predatory mites, with outcomes affected by body size and behavioral traits. Abstract BACKGROUND Cannibalism and intraguild predation (IGP) are common interactions among predators that can influence the effectiveness of ...

Effect of Schinus areira L. Essential Oil on Attraction, Reproductive Behavior, and Survival of Ceratitis capitata Wiedemann

Plants
The essential oil (EO) of Schinus areira exhibits a chemical composition dominated by monoterpene and sesquiterpene hydrocarbons, with α-phellandrene, limonene, α-pinene, and p-cymene as major constituents.

Transcriptomic resources and functional validation of RNAi in the cabbage seedpod weevil, Ceutorhynchus obstrictus

Pest Management Science, EarlyView.
Transcriptome sequencing of Ceutorhynchus obstrictus revealed RNA interference (RNAi) targets; double‐stranded RNA microinjection reduced transcript levels and increased mortality, with αCOP and Rop showing strongest lethal effects, indicating promising RNAi‐based pest control candidates.

Effects of Geraniol on Survival, Reproduction, Endophytes, and Transcriptome of Tea Green Leafhoppers (Empoasca onukii)

Agronomy
Herbivore-induced plant volatiles (HIPVs) serve as powerful defense mechanisms that help plants mitigate pest-induced stress. Geraniol is a HIPV released by tea leaves in response to damage inflicted by tea green leafhoppers.

Modelling the phenology of the grapevine leafhopper Erasmoneura vulnerata

Pest Management Science, EarlyView.
This study developed and validated a phenological population dynamics model for Erasmoneura vulnerata, integrating field monitoring and literature data to reproduce observed seasonal patterns across multiple sites. Abstract BACKGROUND Erasmoneura vulnerata (Fitch) (Hemiptera: Cicadellidae) is an invasive Nearctic leafhopper that has become a pest of ...

Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae

Pest Management Science, EarlyView.
Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.
